WASHING momia Application led December 27, 1921. Serial No. 524,878.

To all 'whom it may. concern.'

Be it known that I, J ULIUs H'. KINTZELE,

a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented new and useful Improvements in Washing Machines, of which the followinwis a specification.

his invention rela-tes to washing machines. Y

An object of the invention is to provide a washing machine including a pair of wash chambers and novel mechanism for operating plungers in the chambers for cleansing the clothes.

Another object of the invention is to provide a washing machine includin a pair of plungers operating in separate c ambers, a rocking device for operating the plun ers, a driving gear, and novel connection rom 20 the driving gear for operating the rocking device, with provision for obtaining a yielding or cushioning eiect to avoid strain upon any 0f the Parts# Another object is to improve generally the construction and mode of operation of the washing machine herein shown and de scribed. In the drawings l Fig. 1 is an elevation, with parts broken away, showing one embodiment of the invention.

Fig. 2 is an enlarged view showin the mounting of the rocker arm by whic the plungers are operated.

Fig. 3 is a lan view of the same.

Figs. 4 an 5 are views of the clutch device for controlling the lever by which the rocker arm shaft is supported and operated.

Fig. 6 is a sectional view showing the construction and arrangement by which the 40 rocker arm is removably supported in connection with its shaft.

In the embodiment of the invention shown the machine comprises a frame 1 supported on caster rollers 2 so that the entire machine is easily movable from one position to another. The tub 3 may be composed, of sheet metal as shown, or of other appropriate material, and is removably supported upon the ilan es 4 extending inwardly from the metalp lic ame 1. The tub is provided with a removable lid or cover 5 having a depending flange 6 extendin into the tub and is also provided with a andle 7 whereby the lid or cover may be moved.

The tub is divided into two compartments or chambers by a vertical partition 8 rising from the bottom wall of the tub and extend 1n entirely across from one side wall to the. ot er. Holes or passages 8 are provided in the partition 8 near the bottom of ther tub to permit flow and surge of the, water "r from one compartment to the other when the machine is in use. A valved faucet 8h is provlded at one side of the tub to drain out the water.

A horizontal shaft 9 is supported forrocking movements near the top of the tub above the partition 8. A rocker arm lO is supported "on the shaft .9 midway between the side walls of the tub. A rocker arm ei;- tends about tothe vertical axis of each of the chambers in the tub. The middle portion of the rocker arm is formed with a loop 11, each side of which has a laterally extended hub portion. 12. AV vertical notch 13 is formed in the under side of the loop and of the hub members and receives a fiat portion 14 of the shaft9.` The flat portion 14 is formed by a pair of notches, one of which is at each side of the shaft 9, the thickness of the fiat portion being about equal to the widthof the notch 13. The rocker arm is placed u onthe shaft 9 with the iat portion 14- wit in the notch 13 so that the rocker arm must rock with the shaft. A retaining device for holding the rocker arm iny connection with the shaft comprises a hook 15 pivoted'upon a pin 16 supported by the loop 11 above the shaft 9 and arranged to engage under said shaft asshown in Fig. 2. To actuate the hook to a position to engage under the shaft a springl'- is provided, but s'aid spring will yield when pressure is ap lied t'o the free end of the hook 15 in or er to permit the hook to be disengaged from the shaft. vA pin 18 supported by the loop 11 formsa support for the hook 15.

An arm 19 is pivotally connected to each end of theY rocker arm 10 by a removable pin or boltl 20. l,A plunger 21 in the form of an inverted bowl is supported by each of the swinging arms 19 and is capable of different adjustments. Each of the plungers 21 is rovided `with a vertical sleeve portion 22 adapted to receive the lower end of the corresponding member 19. Each arm 19 is formed with a number of holes 23 for receiving the supporting p'in 24 passing through corresponding holes in the sleeve portion 22 in order lto support the plunger,

in connection with the arm. A spring 25 in connection with each of the sleeve portions 22 holds the pin 24 from displacement. Each plunger may be raised or lowered on its supporting arm 19 byremoving' the pin 24 and raising or lowering the plunger as desired and reinserting the pin.

The outer end of the shaft 9 pivotally supports an arm or lever 26 having a clutch portion 27 in connection therewith. A clutch member 28 feathered on the shaft 9 is movable into and out of engagemnet with the clutch `27 For this purpose-'a shift device comprising a rocking rod 29 is provided, the same being supported in bearings 30 and having a crank 31 engaging the clutch member 28. A lever 32 on the end of the rod 29 affords convenient means for turning the rod to move the clutch member 28 into and out of clutching engagement with the clutch 27.. Obviously, when the clutch member 28 is out of engagement with the clutch member 27, the arm or lever 26 is free to operate without rocking the shaft 9, but when the clutch members are engaged the shaft 9 will be operated by the lever 26. 1

The operating mechanism shown comprises a motor 33 arrangedto drive a belt 34 passing around a belt wheel or pulley 35. The belt wheel or pulley 35 is supported upon a shaft 36 having a small gear 37 thereon meshing with a arge gear 38 on a shaft 39. The shaft 39 has an larm 40 attached thereto. A pitman connection in the form of a frame 41 has one end pivoted to the arm 40. A rod 42 is supported for movement within the pitman frame 41 and has its upper end pivoted to the lever 26. A spring 43 encircles the rod 42 within the Pitman frame 41 and has its upper end bearing against the upper end of the pitman frame and its lower end bearing against a collar 44 on the rod 42. Another spring 45, alsoencircles the rod 42 and has its lower end bearing against a cross member 46 of the pitman frame and its upper end bearin against a collar 47 attached to the rod 42.

It is obvious that these connections from the drivin mechanism to the rock shaft form effective cushioning devices so that the parts of the machine will not be subjected to strains or undue stresses when the machine is operated. Should the clothes in one of the compartments of the tub become rolled or packed, the machine will continue to operate properly even though movement of the plunger-is stopped b the clothes. The springs 43 and 45 will yie` d to permit proper operation of the driving` mechanism without corresponding 'movement by the shaft 9 and the rocker arm 10. That is, while the extent of movement of the pitman frame 41 is the same at each operation, the extent ot movement of the rod 42 by which the washig mechanism is operated varies.

The machine is also equipped with wringer operating mechanism. As shown, the shaft 39 has a beveled gear 48 thereon meshing with a beveled gear 49-on the lower end of a shaft 50. A frame 51 for supporting the wringer frame 52 is centered on the shaft 50 and may be turned to different positions to swing the wringer frame 52 to different adjusted positions. A ylatch plate 53 is attached to thel frame 1 below the frame 51 and is formed with a number of holes 54 for receiving a latch bolt 55 mounted in the frame 51, and actuated to a latching position by a spring 56 and from latching position by a lever 57.

From the foregoing it will be seen that my invention obtains all of its intended objects and purposes in a highly convenient, eiiicient and satisfactory manner. The plungers 21 may be easily adjusted in connection with their operating arts for use in washing large or small batclges of clothes. The yielding connection between the driving mechanism and the washing mechanism obtains satisfactor operation of the washing mechanism un er widely varying condi tions.

It is apparent that the invention-may be varied in numerous particulars without departure from the nature and principle thereof.
